To all :cham it may concern:

Be it known that I, Aunzn'r l". Kaarst-1.1i citizen of the United Statesresiding at Butl'alo, in the county of Erie and State of New York, have invented a new and usel'ul Improvement in Vacuum Cleaning Apparatns, of which the following is a .specilication.

'l`his invention relates to a vacuum cleauing apparatus desi 'ned more particularlyl for household use aaizl adapted to be operated bv water-[mwen 'lbe cleaners now genera ly employed for this purpose are objectionable in that they necessitate the handlin f of the dust und other accumulations whicli are discharged into ldust-collectors or receptacles with .which they are usually provided. Moreover, such dust collectors or separators. do not thoroughly separate the dust from the air, and sinne of the dust therefore tiuds its way back into the. room, when the machine is of the portable type suitable for household nse. liurtheriuore, the larger cleaning machines and a iparatus now in use are so complicated ani expensive as to be beyond the reach of the onlmary luniseliolder. while those of the smaller band-o ierated type require two persons to properly operate them, one to actuate the pump nml the other to guide the nozzle.

(luc ofthe objects of my invention is tlec provision of a vacuum cleaner which obviates the nis'essity of handling the dust act-ir nuilations in any forni, and which is not liable to become clogged.

Further objects are the production of a compact. and portable cleaner which can be operated by water power which is gcncinlly available in dwelling houses; \\hieli can be produced at a ligure to bring it within the reach of the ordinary household. and which is so simple in instruction and reliable in operation that it can lic uit in service and used by peisons ordinari .v iuisltilled in tlie use of inachiues.

lu the accompanying drawiuifs Figure l is a sectional |u-rs|nsftive view olrau embodinient of the cleaning apparatus. Fig. 2 is a longitudinal section ol' the nozzle.

Similar letters ol rcl'erencc indicate corresponding parts in both views,

A ildcates a stationary suction or vacuum chamber containing a rotary suction fan ll and mounted upon standards or pedestals (l, (3' by which it is supported in n sinh l),

or a tub or simila r receptacle connected with a drain orse\ver. 'Ihe shaft l of the fau is preferably horizontal and journaled in suitable bearings b, b. The suction chamber is provided at its suet ion side with a redun-d extension or inlet tube a towhich is counectcd a hose or tlcaible eoinliiit lI terminating in a suitabh,l eczzlc l". 'lhe nozzle shown in the drawiirrs by way of example` is tlared and provided with a laterally-extemled face-plate having u )turned front and rear edges and a narrow ongitudiual inlet slot f. This nozzle is moved over the carpet or other surface to hekelt-uned, in a well-known manner.

y indicates a liquid motor or water wheel mounted on the fan-sha ft (i and arranged in a case pirferalily mounted at the upper cud of the pedestal C.

/r indicates il jet-nozzle which enters the motor casing at the proper angle to direct a water-jet against the buckets of the wheel (l for driving thc saine and the suction fan, or ispiivaleut exhaust device. 'lhis jet-nozzle ina be munoi'zted with any available source of liquid under pressure. When the a iparatns is used for instance in a dwe ing house, this nozzle may be connccted with the usual faucet l of the serviecipe b v a de' tacliable hose i or other suitalille conduit.

('-onnecled witlithe discharig sidool' the motor case (l is :i mixing chamber or tube .l which is preferably formed by the hollow or tillnilar |wdcstal (l, which latter is open at its lower cud alul elevated by feet C, so as to discharge the dust-liiden water into the sink l) or other receptacle in which the appariitus is placed or with which the delivery end of the mixing tube may be conuccted.

l.- indicates a dust-tube or conduit connecting the discharge side ol' the suction chamber with the mixing tube J.
